Ads are not blocked when --enable-features is used on production

[btlechowski]

We should block ads when --enable-features is used on production. This is a regression.

Steps to Reproduce

1. Clean profile
2. Run Brave with

--enable-logging=stderr --vmodule="*/variations/*"=6,"*/bat-native-ledger/*"=6,"*/brave_rewards/*"=6,"*/bat-native-ads/*"=6,"*bat-native-confirmations/*"=6,"*/brave_ads/*"=9,"*/brave_user_model/*"=6,"*/bat_ads/*"=6 --enable-features="UserActivity:threshold/0.0"

3. Enable rewards and ads
4. view an ad

Actual result:

able to view an ad

This is a change in Chromium, and I am investigating a fix.
